Iran's presidents have defined the Islamic Republic's attitudes towards the rest of the world. Never has this been more true than now. In this book Siavush Randjbar-Daemi presents an in-depth analysis of the evolution of the Iranian presidency from its inception in the aftermath of the Islamic Revolution to the present day. He offers detailed narratives of each president's ascent to the post and their struggles to acquire authority andmaintain relevance within the political process. The figures under consideration include the widely-admired Mohammad Khatami, the internationally-criticised Mahmoud Ahmadinejad and the incumbent president Hassan Rouhani, who steered the decade-long nuclear confrontation between Iran and the West towards a diplomatic conclusion.This book sheds light on the extraordinarily complex workings of the Iranian state, taking into account both the opportunities and challenges that each president has faced whilst in power.
